With triethylamine;dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; at 110.0℃; under 75007.5 Torr; for 20.0h; | To a solution of 2-bromo-5-fluoro-3-methyl-pyridine (4.90 g) in AcOEt (100 ml) and MeOH (10 ml) was subsequently added NEt3 (5.4 ml) and 1,1 '- bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane adduct (490 mg) and the mixture was carbonylated at 100 bar CO and 110C for 20 h. The mixture was evaporated and the residue purified by chromatography on silica gel using n- heptane/ AcOEt (7: 1) to give the title compound (3.44 g) as a pale red solid. MS: m/z = 170.1 [M+H]+. | |
